F 15 BTTORNE Y Patented Mar. 7, 1933 UNITED STATES PATENT OFFICE WILLIAM JOSEPH BUTTERVTORTH, F TUT'BURY, ENGLAND, ASSIGNOR 'IO QUALCAST LIMITED, OF DERBY, ENGLAND, A COMPANY OF GREAT BRITAIN WASHING MACHINE Application filed June 24, 1932, Serial No. 619,155,.and in Great Britain June 8, 1931.

means of chains or like flexible members which are wound round the shaft and pulled alternately in opposite directions.

The object of the invention is to provide an improved construction of such kind of washing machine.

A washing machine of the kind set forth, constructed in accordance with this invention,'comprises a dolly mounted on a vertical shaft and a handle mounted on an horizontal shaft, said horizontal shaft being formed or provided with two oppositely opposed sectors to the peripheries of which and to the vertical shaft of the dolly are secured two flexible elements.

The said flexible elements may be metal strips, wire or hemp ropes or chains.

In order that the invention may be fully understood, it will now be described with reference to the accompanying drawing in which Figure 1 is a front elevation, partly in section, of one form of washing machine constructed in accordance with this invention; Figure 2 is a sectional plan view; Figure 3 is a section on the line 33 of Figure 1, and Figure 4 is a section on the line 44 of Figure 1.

w is a tub or container preferably composed of galvanized metal.

I; is a bridge spanning the top of the tube a. Said bridge, which may be composed of wood or metal, or of a combination of wood and metal, is inverted U-shape in cross section in the present example, although of course it may be of any other suitable crosssection. The said bridge I) is both hingedly and detachably connected to the tub a. 0 is a block pivotally mounted at d, d in the sides I), b of the bridge. Said block 0 is formed with a central aperture 6 which takes over a peg 7 provided at the edge of the tub a. With this construction, the bridge I) can be raised upward, say through an angle of 180 if desired, and moved to either side.

9 is a hook to retain the bridge in position.

The dolly k, which is of the usual construction with, say, four pegs, is provided with a shaft j. This shaft is retained in a slot. in the drum is which is rotatably mounted in bearings Z, Z, housed in the top and bottom of the bridge I). The position of the dolly h in the tub a can be regulated by means of the adjusting collar and screw m.

a is a handle adapted to fit in the hub 0 which is rotatably mounted on the horizontal axis p mounted in horizontally arranged elongated slots g in the two sides of the bridge I). The purpose of these slots will be explained hereafter.

Formed on the hub 0 are two oppositely opposed sectors 1", 7*. On the periphery of each of the said sectors 1" is secured one end of a chain, the other end of which isarranged to pass partially around the drum is and be secured thereto. Each chain, which ispreferably of the roller type, is composed of two sections 8, s, the links of one section 8 being arranged in a plane at right angles to that of the other section 3. Such an arrangement is necessary, because the axis of the drum k is at right angles to the axis of the sectors r. The sections 8, s, of the chain pass around the drum is in opposite directions.

The purpose of the said slots q is that the axis p may be moved therein in order to,

take up any slack in the chains 8. Winged nuts t, t, retain the axis p in the desired position.

It will be seen that the to and fro movement of the handle it will cause the semirotary movement of the dolly it.

When it is desired to remove the washed articles from the tub, the hook g is unfastened and the bridge may be removed entirely, swung back about the peg f, or moved either to the right or to the left.

What I claim is V In a machine of the character described, a bridge having a pair of opposed elongated slots formed therein, a driven shaft vertically mounted for rotation in' said bridge, a driving shaft horizontally mounted for rotation in said bridge and disposed for sliding movement within the elongated slots of the latter, means associated with said driving shaft whereby to lock the same in adjusted position Within the elongated slots of the bridge, a pair of sectors fixed in in- 5 verse opposed relation upon said driving shaft, and a sectional chain secured to each of said sectors and to said driven shaft whereby to transmit the oscillatory movement of the driving shaft to the driven 10 shaft, the links of one section of the chains being in a plane at right angles to the links of the remaining section.

In testimony whereof he afiixes his signature.
